In this inspiring memoir, a young American doctor struggles to save one desperately poor young patient in rural Haiti who has the largest brain tumor any neurosurgeon at a major Harvard teaching hospital has ever seen. Dr. Aaron Berkowitz, an idealistic Harvard Medical School neurologist, went into medicine to build bridges between a very rich world and a very poor one. The ups and downs, and the reverses and triumphs of trying to accomplish this dream make this a case study for how any of us choose which good actions to take on. In the vein of Bryan Stevenson and Matthew Desmond, Abraham Verghese and Oliver Sachs, Dr. Berkowitz explores what it was like as a young doctor trying to make the first big save of his career in the midst of devastating inequity and poverty.
